(A and B) Western blot analysis of the conditioned medium and cell lysates from WT thalamic neurons in response to 5 nM Sema3A-Fc.
(C and D) Quantification of the western blot analysis for soluble CHL1 (sCHL1) and APP C-terminal fragment β (C99).
(E) Schematic representation of BACE1 cleavage site on CHL1 (Gln1061/Asp1062).
(F and G) Analysis of Sema3A-induced growth cone collapse in Chl1−/− thalamic neurons transfected with empty vector, Fl-Chl1, and Fl-Chl1 and treated with 1 μM CIV or with non-cleavable Chl1D1062H.
Results are presented as mean ± SEM. The scale bars represent 5 μm. See also Figure S2.
